Hydrogen is the first element in the periodic table, meaning it has an atomic number of 1 or 1 proton in each hydrogen atom. The name of the element comes from the Greek words hydro for "water" and genes for "forming," since hydrogen bonds with oxygen to form water (H 2 O).

Answer (1 of 3): The other answers to date are, I'm afraid, wrong - the reason hydrogen is not used is not because it is flammable. Oh, sure - hydrogen elicits the knee-jerk response of explosions and fires and danger, but that's not borne out by reality. In the Hindenburg crash, for example, alm...
